Evaluate the expression when c = 6 and x = -2.
c-6x
Answer:
18
Step-by-step explanation:
C = 6 and x = -2 just mean that you are supposed to substitute them into the equation.
That means that the equation should be: 6 - 6 * -2, or 6 − 6 (−2), or 18.
Hope that this helps!
39
125°
Find the value of x
Answer:
Step-by-step explanation:
The sum of the interior angles of this triangle must be 180 degrees.
Thus, angle x is 180 degrees less (39 degrees plus 125 degrees), or
x = 180 degrees - 164 degrees = 16 degrees.
Because of the 125 degree angle, this is an obtuse triangle.
question involving radius and arcs. need help
does 4(x+1)=2x+4 have a solution
Answer: Yes, x = 0
Step-by-step explanation:
To solve for x, we will simplify things by distributing the 4 to the (x + 1) term. This means that our new equation will be
4x + 4 = 2x + 4
Now that we have our new equation, we will isolate x by subtracting 4 from both sides. After this, we will end up with
4x = 2x
At first glance, this may seem like no solution. What number has the same value when multiplied by 2 and by 4? Well, there infact is one. This can be shown when we subtract both sides by 2x to keep x on one side, and get
2x = 0
Divide by both sides to isolate x, and you get x = 0/2 = 0.
Thus, x = 0.
how to find MP when discount percent and SP are given
Given:
Consider the discount percent and SP are given.
To find:
The MP.
Solution:
Let x% be the discount percent Then
[tex]SP=MP-x\%\text{ of }MP[/tex]
[tex]SP=MP-\dfrac{x}{100}MP[/tex]
[tex]SP=\left(1-\dfrac{x}{100}\right)MP[/tex]
[tex]SP=\left(\dfrac{100-x}{100}\right)MP[/tex]
Multiply both sides by 100.
[tex]100SP=(100-x)MP[/tex]
Divide both sides by [tex](100-x)[/tex].
[tex]\dfrac{100}{100-x}SP=MP[/tex]
Therefore, the formula for MP is [tex]MP=\dfrac{100}{100-x}SP[/tex], where x is the discount percentage.

Answer:
2 2/3 square inches
Step-by-step explanation:
Since each side equals 2/3 of, say, an inch, you need to multiply 2/3 by 2/3 to get the area of one side, then multiply that value by 6 to get the total surface area.

Which of the following expressions is equivalent to the logarithmic
expression below?
In 5 + In 3
Answer:
Ln 15
Step-by-step explanation:
The expression equivalent to ln(5) + ln(3) is logarithmic ln(15), which is option C.
What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
Given expression,
In 5 + In 3
We can use the logarithmic identity that says:
log(x) + log(y) = log(xy)
Using this identity, we can rewrite the given expression as:
ln(5) + ln(3) = ln(5 × 3) = ln(15)
Option A, ln(5³) is equivalent to ln(125), which is not the same as ln(15).
Option B, ln(8) is not equivalent to ln(5) + ln(3).
Option D, ln(3⁵) is equivalent to ln(243), which is not the same as ln(5) + ln(3).
Therefore, the expression equivalent to ln(5) + ln(3) is ln(15), which is option C.

Use technology or a z-score table to answer the question.
The weights of books in a bookcase are normally distributed with a mean of 11.6 pounds and a standard deviation of 1.3 pounds. There are 136 books on the bookshelf.
How many of the books will weigh 10 pounds or more?
A. 109
B. 116
C. 121
D. 130
The number of books that will weigh 10 pounds or more is 121. Then the correct option is C.
What is a z-score?The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The weights of books in a bookcase are normally distributed with a mean of 11.6 pounds and a standard deviation of 1.3 pounds. There are 136 books on the bookshelf.
Then the z-score when the books will weigh 10 pounds or more will be
[tex]z = \dfrac{10 - 11.6}{1.3}\\\\z = -1.23077[/tex]
Then the probability will be
[tex]\rm P(x > 10) = 1 - P(x < 10) = 0.8909 \ or \ 89.09\%[/tex]
89.09% of books will weigh 10 pounds or more, then the number of the books will be
→ 136 × 0.8909
→ 121.1624 ≈ 121

Joshua and Kay are out for a walk on a
rainy day. They come to the edge of a large,
circular puddle that has a radius of 3 feet.
Joshua is wearing boots, so he walks straight
through the center of the puddle to the
other side. Kay forgot to wear her boots, so
she walks around the outside of the puddle
to meet Joshua on the other side.
How much farther, in feet, did Kay walk
than Joshua? (Use 3.14 for π.)
Answer:
3.42 feet
Step-by-step explanation:
Joshua walked 3 x 2 = 6 feet
Kay walked approximately (3.14 x 6)/2 or 9.42 feet
9.42 - 6 = 3.42 feet
Kay walked 3.42 feet further than Joshua.
Using a six-sided die, you have rolled a 6 on each of four successive tosses. What is the probability of rolling a 6 on the next toss?
Answer:
The probability of rolling a 6 on the next toss = 1/6
Step-by-step explanation:
Given - Using a six-sided die, you have rolled a 6 on each of four successive tosses.
To find - What is the probability of rolling a 6 on the next toss?
Proof -
As the outcomes of previous rolls do not affect the outcomes of future rolls.
And there is one desired outcome and six possible outcomes.
So,
The probability of rolling a six on the fifth roll = 1/6 which is same as the probability of rolling a six on any given individual roll.
So,
The answer is -
The probability of rolling a 6 on the next toss = 1/6
In a six-sided die, by rolling a 6 on each of four successive tosses. the probability on the next toss is 1/6.
A six-sided die rolled 6 on each of four successive tosses.
What is probability?It is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The number of favorable outcomes of the die is 1 and the total number of outcomes of the six-sided die is 6.
So, The probability of rolling a six on the fifth roll = 1/6, which is the same as the probability of rolling a six on any given individual roll.
The probability of rolling a 6 on the next toss = 1/6.
